Asshown,:.-thea member In zterminatesiat onezextremityitheredf in anextension?providingispaced furcations 'IIQJELHCIJZQ Linclined.relative'thereto. "It 50 is to be noted thataitheifurcations 1'9 and.ZIL-are spaced-along aslongitudin'al .medianline of the member H0 andthere is tan enlarged icircular opening 2| .providedinthe 'regionofjoinderfor :communication withitheispace between-the-furca- 55 tions l9and 20 so as to provide clearance for the carving tool and to affordinspection thereof while in operation. A carving tool 22 of any desiredconfiguration or design is mounted between the furcations l9 and 26 soas to dispose the carving or cutting edge 23 thereof below the bottomsurface ll of the handle member Hi to effect the grooving or carving ofthe surface l2 over which the member it is displaced.

To this end, the carving tool 22 is preferably of substantially U-shapedconfiguration so as to define upstanding arms terminating in laterallydirected fianges 22. and 25 which are spaced to rest on the top surfaceof the furcations l9 and 20. With this arrangement, the substantially U-shaped arms and curved base of the cutting or grooving tool 22 dependsdownwardly from the furcations l9 and 2!] so as to occupy the spacetherebetween and dispose the cutting edge 23 below the sustainingsurface ll of the member Hi.

It should be observed that the substantially U- shaped carving tool 22has a curved base 26 which is in parallelism with the laterallyextending fianges 2 3 and 25 so as to impart the same inclinationthereto as possessed and defined by the top surfaces of the furcationsI9 and 20. In order to securely mount or attach the carving tool 22along the inclined furcations l9 and 20 in any adjusted position, plates21 and 28 are provided to conform with and confront the furcations I9and 29 so as to secure the flanges 24 and 25 against the furcations l9and 20.

To this end, fasteners such as threaded studs 29 project through theplates 2'! and 28 so as to engage correspondingly threaded aperturesprovided in the furcations I9 and 28, thereby securing the carving tool22 in any adjusted position along the inclination of the furcations i9and 20. The position of the carving tool along the furcations l9 and 22determines the position of the severing or cutting edge 23 relative tothe bottom sustaining surface 1 l of the member 10. In other words, thedepth of the groove or out effected by the tool 22 can be varieddepending upon the position thereof along the inclined furcations l9 and20. The form of the groove or carvings may vary depending upon theconfiguration of the cutting tool 22 and the position thereof along thefurcations l9 and 20 relative to the sustaining surface I! of the memberID.

The configuration or design of the cutting tool 22 may vary within awide range depending upon the dictates of commercial practice. As anexample thereof, Figure 6 shows a carving tool 22 of substantially W-shaped design so as to create a groove corresponding in configurationtherewith. This carving tool 22' still has the upstanding arms andlaterally directed flanges similar to the carving device 22 describedsupra. In a modified form (Figure 8) the member I is provided with apair of inclined furcations |9'20 and I92fl" at both ends thereof, thesebeing preferably of different inclinations and of different size so asto accommodate different types of carving tools of varying capacity andconfiguration. Otherwise the structural features are identical and theprinciple remains unaltered.

In the modified embodiment shown in Figure 10, the carving tool orcutter 22" is mounted be. tween furcations I9" and 20" constituting apart of the member l0" which has a flat portion H" and a raised orinclined extension l8" terminating in a handle member H". In thisdevice, the furcations l9"20" and the inclined portions B8 are more orless diverging to present the cutter or carving tool 22 clearlyaccessible to corners, curved surfaces and restricted locations where adevice of the type described supra would be inaccessible and incapableof operation.

Special design tools may be provided for any particular or special work,and such may take a variety of forms depending upon any individualproblem or upon the dictates of commercial practice.

In operation, the substantially flat member i0 or iii is displaced overa surface so that the carving devices 22 and 22 gouge into the wood,leather or other type of surface it so as to form a groove or grooves 30with the material 3| thereof being removed in a continuous unitary piececonforml5 ing in configuration with the groove 38 left in the articlei2. The groove 38 may be along straight lines when guided by a T-squareor other straight edge 32 or along curved or circumferential paths Whenguided by a member 33 having a bracket 34 at one extremity thereof fordetachable association with the member ill or Iii.

To this end, the member Ill or H) is provided with a pair of spacedapertures 35 which are threaded to receive screw fasteners 36 adapted toproject through the bracket 34 of the member 33 for securing such tothehandle member Hi. As shown, the elongated member 33 is provided with alongitudinal series of apertures 3'! for receiving a pin or nail 38therethrough to serve as the fulcrum along which the carving member IDis displaced in a curved path 39.

The effective radius of the elongated member 33 may be varied dependingupon the position of the pin 38 therealong, and numerous types ofstraight, curved or irregular figures may be provided or effected inthis manner. The surface l2 may be grooved and the ornamentationprovided in this form or the strip of material 3| removed in consequencetraversing the carving member 40 it] along the surface l2, or may beagain utilized in conjunction with the groove 30 from which it isformed. In effecting the desired groove the strips of material 3| areremoved intact, and colored or otherwise treated to present a differentappearance from its original condition or state. Thereupon, it can bereplaced for filling the groove 30 (Figure 9) so as to provide an inlay,thereby imparting the desired ornamentation and configuration to thesurface I2. 50,

The nature of the ornamentation may be varied within a wide range andthis is likewise applicable to the carving tool 22 which can take manyforms depending upon the dictates of the individual.

With a device of this character, it is unnecessary 55.

to provide a skilled artisan for accomplishing the desired surfaceornamentation and such can be effected speedily and Without entailingany appreciable labor, material or time. Various changes may be made inthe embodiment of the 0 invention herein specificially described withoutdeparting from or sacrificing any of the advantages of the invention asdefined in the ap pended claims.

I claim:
